ThreadPool::enqueue() failed to forward an argument as reference

[wanlizhu]

for example, the following test case will fail:

TEST(ThreadPool, Case1) {
ThreadPool pool(4);
int x = 1;

    auto res = pool.enqueue([](int& y){ y = 99; },  x);
    res.get();

    EXPECT_EQ(x, 99);

}

I think std::ref is needed here. https://en.cppreference.com/w/cpp/utility/functional/ref

Thanks for your answer, it is correct now

could you please close this issue, as it seems solved now?
